Half of the 10 worst cities in America to live are in Tennessee and Georgia, and most of the others aren't far from them, according to a study RoadSnacks.com that analyzed 250 municipalities by population density, unemployment, income, education and crime.

Macon in Georgia tops the website's list of the 10 worst places to live while Savannah comes in at No. 7. Tennessee has three cities on the list – Knoxville at No. 4, Chattanooga at No. 5 and Memphis at No. 8.

Jackson in Mississippi is ranked No. 2 on the list and Mobile in Alabama is No. 9, giving the South seven out of the 10 worst cities in America to live

"They are the places that aren't safe, that have bad economies, and places where the school systems are in bad shape," said Nick James of RoadSnacks.com. "If a city has lots of people out of work, and poor income levels, it's not desirable."

"If home prices are low, there's not a lot of demand to live there. And if crime is really high, no one wants to be there. The cities … all share those qualities," said James.

RoadSnacks.com said it used statistics from FBI crime data, the U.S. Census bureau, the Bureau of Labor Statistics, and Sperling's Best Places.

The other three worst cities to live are Detroit (No. 3), Rockford, Illinois (No. 6), and Springfield, Missouri (No. 10).

Detroit and Memphis are the only repeats in a similar study by Destination Tips.com posted online last October. That study used crime reports, incomes, poverty levels and unemployment, along with climate and air quality. Detroit was No. 2 and Memphis was No. 5 then.
